Two-high mills are used in pickle lines, galvanizing lines, and skin pass mills. The large diameter rolls allow for a large roll bite. This means the material can be soft, such as hot steel that can be reduced from slab to plate in a single pass with large reductions. This cannot be done with small diameter rolls. This is why 2-high mills are used in the rubber and plastic industries. They are
